Ox or Vf signal to tap for simulating 02?

That's true but consider other conditions. For example if you climb a grade with partial throttle and boost it may not go to 70% and open loop. Instead it may go boom...

yes, this is one area I was always a bit fuzzy on. I know i can hit boost easily at basically any throttle point with that little ct still on there. Typically the afrs go into the 13's no matter what SAFC settings i use with boost and part throttle. This has always been a concern as i'm not really sure how to tune for these conditions
